SHUTTER-CARRYING SHIELD.

Application filed October 14, 1920, Serial No. 416,889.

To all whom it may concern:

Y Be it known that I, Crunnns A. ll IBERG,

a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented a new and Improved Shutter-Carrying Shield, of which the following is a specification.

My invention has reference to improvements in means attachable to motor vehicles for regulating the air circulation through the radiator and which is particularly designed for being applied to the conventional shapes of radiators for use in cold weather, when the air is too cold to pass through the radiator unobstructed.

Among other objects, my invention has for its purpose to provide a draft controlling shield for radiators of a relatively simple and economical construction, in which the several parts are so combined and operatively connected, whereby they may be readily adjusted for causing the air to pass through the entire radiator, on through parts thereof, or prevented from passing through the radiator at all as conditions may make desirable.

With other minor objects in view, the

v nature of which will be apparent from the following detailed description, my invention comprehends an improved draft or shutter attachment for radiators which, when applied to the ordinary types of radiators, presents a neat and attractive appearance, does not change the usual lines of the car design and which embodies the peculiar features of construction and novel combination of parts, all ofwhich will be fully brought out in the detailed description, specifically stated in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my shutter carrying shield orattachment for radiators, the same being shown as applied to a radiator front.

Figure 2 is a vertical section thereof taken substantially on the line 2-2 on Figure 1', so much of a radiator and a portion of "the motor car power mechanism being indicated to illustrate a practical application of my invention, the different sections or shutter units being shown at different adjustments, one at the fully opened, one at a partly opened, and the other at a fully closed position.

lligure 3 is a horizontal section of the shutter carrying shield or attachment taken substantially on the line I-l$-l on Figure 1.

Figure 4 is a detail vertical sectiontaken on the line +t-l of Figure 3, that illustrates the shutter shifting levers and the rack and spring devices for holding the shutter sections or units at the adjusted positions hereinafter explained. I

Figure 5 is a detail perspective view of one of the clamp devices that secure the shield to the. radiator hood or cover.

Figure 6 is a detail view of a portion of one of the shutter blades with a part of a closure lining attached thereto.

Figure 7 is a detail perspective view of one of the bushings for the shutter pintles.

Figure 8 is a diagrammatic plan view of a somewhat modified form of theshutter blades hereinafter specifically referred to.

Figure 9 is a detail section which illustrates a modified means for shifting the shutter units to the partially or wholly opened or closed adjustments.

Figures 10, 11 and 12 are detail "iews of devices hereinafter specifically referred to; v

and adapted for effecting adjustment of the,

shutter units from the car dash.

As hereinbefore mentioned, my shutter carrying shield is especially designed for,

use in connection withmotor car radiators when the air is too cold to pass through the radiator unobstructed, and my said shutter carrying shield is therefore especially designed for being readily attached to the radiator frame or hood for use during cold f weather and also for being quickly detached from the radiator frame or hood during warm weather when not needed.

In carrying out my invention, the general body formation or shape of the shield or attachment, upon which the shutter devices and the means for adjusting such devices are carried, is best indicated by Figures 1 and 3 of the drawings, by reference to which it will be noticed that when applied to the front of the radiator the attachment is securely held over the radiator front by clamp devices 8, the detailed construction of which is shown in Figure 5. A number of such devices 8 is employed and asv each of saiddevices consists of a thinspring' brackets 55 to which two or more clamp devices 88 are attached by the bolts 7-'-7 and by said devices 88 the shield is clamped at the top and bottom along the upper and lowerfront flanges of the radiator hood, as is clearly illustrated on Figure-2.

By referring now to Figure 2, l8 designates the upper and 12 the lower reservoir portion of the radiator and 11 denotes the regular arrangement of radiator pipes and cooling sheets. Referring again to Figures 1, 2, 3 and 4 of the drawings, it will be noticed the shield includes two opposite side frames which are of sheet metal and each of which comprises right angled front and side portions, the front portion 4 extending laterally outward fromthe sides 23 and terminating in narrow back turned flanges 18, the

inner ends of the side members being also' turned laterally and outwardly, as indicated by 1919 and in parallelism with the front walls 4, and to the said members 19-19 are secured, by the bolts 10, the clamp devices 8 by whichthe shield is attached to the radiator frame, as before mentioned. In my construction of shutter carrying means the shutter blades are so mounted and operatively assembled, that, when the shield is operatively applied to the radiator front, they extend in the horizontal plane transversely across the radiator front, the said shutter blades being arranged in sets of units each-composed of a plurality of blades operable in unison when adjusted to their fully or partly opened and closed positions.

In the present, showing of my invention,

- a shutter equipment is shown that is composed of three sets of units and each unit has four shutter blades 2, each of which is' independently pivoted in the opposite sides.

23 23 of the radiator frame, the several shutters of each unit being, however, connected'toa single connecting rod 26, one for each set of shutters, the several rods '26 having such extensions or portions whereby to adapt them for being conveniently manipulated'for settingtheir respective sets of shutter blades to the desired opened or closed positions, as will be presently more fully explained.

Referring now more particularly to Fig ure 4: of the drawings, it will be observed that each of the connecting rods 26, which rods 26 join with one corner 24 of their respective sets of blades (s Figure 6) iucludes an angled portion that extend through elongated slots l iin an adjacent side 23 of the framing, the two uppermost rods 2G-26 having their members :36 pro" jected through a single elongated and curved slot 1 Each of the members 26" merges with a vertical extension 27 positioned adjacent the inner face of the front wall portion 4 of the side 23 having the slots 14;, and each extension terminates in an outwardly extending horizontal finger 28 that is held under tension of a flat spring 30 in contact with a toothed or ratchet rim 32 formed on the inner-edge of the adjacent flange 18 of the frame portion at and to provide for conveniently adjusting the rods 26 and their fcooperating shutter blades each member 28 terminates in a finger knob 28, as shown.

To effect a practically air-tight closure of the shutter units, when their blades 2 are in the closed position, as indicated at the bottom of Figure 2, the lower inner edge of each blade has a felt, or other yieldable material, lining strip 15 that is secured, in any approved manner, onto the shutter edge, for example, by making V-shaped incisions through the shutter blade and bending the cut portions back over the top and bottom edges of the lining to form flexible clamps 17 adapted for being firmly pressed over and against the lining strip, as shown in Figure 6, it being understood from Figure 2, that when the blades close against one another, as shown in the lowermost series of units or blades on Figure 2, a practically air-tight closure between the meeting edges of the blades is provided, the several blades when closed forming, as it were, a solid closure across the lower portion of the radiator air ducts, closing off the air entirely through the lower series of air ducts.

While I have shown and described the shutter units as composed each of a series of slats or blades that extend entirely and straightway across the radiator front, it is obvious that the exact formation and arrangement of the several shutter units and the blades embodied in each unit must be dependent upon the particular front shape of: the radiator onto which my invention is to be practically applied. For example, where the radiator fronts are of tapering shape, that is, the opposite sides of the radiator frame are angularly disposed, a separate set of shutter units may be provided for each angled face of the radiator front and the shield and the several sets of shutter units arranged in plan view as indicated in Figure 8. When such arrangement of shutter units is provided the controls 26 may each be attachment for radiators the controls 26* 27- 28 utilized for setting the shutter blades to their adjusted positions, may be readily operated from the dashboard or seat of the car by suitable means including detent devices under control of the driver for holding the shutter control devices at their adjusted positions. For example, the several controls 26 may each be spring returned to one position by springs 33 arranged shown 1n Figure 9, and pulled to their opposite adj'ustment or position by cables 34 that'are caused to pass over guide pulleys 85 which are suitably placed on the radiator drums and from which they each pass to an individual drum 36 which in practice may be mounted on a common stud bearing 37 located in a housing 38 secured to the dash, as indicated in Figures 11 and 12, by reference to which it will be seen each drum 36 has an individual operating or turning finger 39 and the several fingers 39 pass through individual segmental slots 40 in the housing front, one edge ofeach of which has notches 41 for locking the fingers 39 therein after the shutter shall-have been adjusted, as desired.

From theforegoing description, taken in connection with the drawings, the general construction, the manner in which the parts may be conveniently and operatively applied to a radiator frame will be readily apparent to automobile users.

By reason of the peculiar manner in which the several shutter units are mounted wlthin the frame portions that constitute the shield and which latter is easily at- I tached to or removed from the radiator frame by proper adjustment of the clamps 8, any one of the shutter units, by pulling the control rods 26-;27 fully or partly up or down, may be set to the partly open, wholly open or entirely .closed adjustments, as shown in Figure 2, and to which ad justments they are securely held by holding the handle members 28 in interlocked engagement with the edge 32.

While the detailed arrangement of parts shown and described illustrate a practical exemplification of my invention it is understood that the details and the exactcorela tion of the parts shown may be readily modified or changed to suit the special requirements that may be necessitated by the specific construction of radiator frame to which the attachment is to be applied, without departing from the spirits of the invention as comes within the scope of the appended claims.
